Help needs - 如何去掉空格

hawk004

hi,

I have a file like this:

IQ_ECUSR_DCRD_DY,None,iqdtcrd.coneuro.dy.1,coneuro.idw.iqdtcrd01.dy,,  None
IQ_ECUSR_DCRD_DY,  IQ_ECUSR_DCRD_DATE_CARD_KSH  ,iqed0du1.trg,None,,
IQ_ECUSR_DCRD_DY,IQ_ECUSR_DCRD_DATE_CARD_KSH,iqed0du2.trg,None,,
IQ_ECUSR_DCRD_DY,IQ_ECUSR_DCRD_DATE_CARD_KSH,iqed1du2.trg,None,,

如何去掉空格 between each "," ? 变成

IQ_ECUSR_DCRD_DY,None,iqdtcrd.coneuro.dy.1,coneuro.idw.iqdtcrd01.dy,,None
IQ_ECUSR_DCRD_DY,IQ_ECUSR_DCRD_DATE_CARD_KSH,iqed0du1.trg,None,,
IQ_ECUSR_DCRD_DY,IQ_ECUSR_DCRD_DATE_CARD_KSH,iqed0du2.trg,None,,
IQ_ECUSR_DCRD_DY,IQ_ECUSR_DCRD_DATE_CARD_KSH,iqed1du2.trg,None,,


Thanks

仅去掉，两边的空格
